Showing they know a thing or two about selling bacon burgers, Burger King Japan has begun offering paying customers the option of super-sizing just the bacon portion of their Whoppers.

For only 100 yen (approximately a buck and a quarter), bacon fiends can get their greasy mitts on 15 extra strips of the good stuff.

That's up to 500% more bacon! And if there's one kind of math I understand, it's bacon math.

The promotion will only be around for a limited time, not unlike the people who take advantage of this promotion.
